ci: limit test workers and remove db:ensure dependency

[jumski]

Limit test workers and remove unnecessary dependency

This PR makes two changes to improve test reliability and build efficiency:

1. Added --maxWorkers=1 flag to vitest commands in the client package to prevent test flakiness by running tests sequentially
2. Removed the db:ensure dependency from the test:unit command in the edge-worker package since unit tests don't require a database connection

These changes should help reduce test flakiness and improve build times by removing unnecessary dependencies.
